Flutter is Google's toolkit for building iOS and Android apps from one codebase. It draws its own interface rather than using each platform's native controls, which means the app looks and behaves identically on both — and ships in roughly 60% of the time two native apps would take.
What is Flutter?
Most cross-platform toolkits translate your code into each platform's native controls, which means the same code produces subtly different results on iOS and Android and you spend real time reconciling them. Flutter does something different: it ships its own rendering engine and draws every pixel itself.
The consequence is that a Flutter app is genuinely identical on both platforms. A button is the same button, an animation runs at the same speed, a layout breaks at the same width. For a business with a design system it wants respected, that is worth a great deal — the alternative is two apps that drift apart over three years of small platform differences.
It is written in Dart, which is unremarkable in a good way: anyone who knows Java, C# or TypeScript reads it immediately.
When we choose Flutter
When the budget has to cover both platforms. Two native apps means two codebases, two teams and two sets of bugs; Flutter means one of each. For most GCC businesses that difference decides whether the app happens at all.
When the interface is the product's identity rather than the platform's. A booking app, a loyalty app, a delivery app — these want to look like the brand, not like iOS. Flutter draws exactly what was designed.
And when both apps must stay in step. A feature shipped once appears on both platforms simultaneously, which removes the familiar situation where Android is three releases behind because it is nobody's priority.
When we do not use Flutter
When the app depends on something only one platform does well — deep HealthKit integration, ARKit, CarPlay, an Apple Watch companion. Flutter can reach native code through plugins, but if half the app is doing that, native was the honest answer.
When the app must feel unmistakably like the platform. Some audiences notice, and a banking app that renders its own controls can read as slightly off in a way that costs trust.
And for a very simple app that is essentially a website in a shell. A well-built mobile web experience costs less and needs no app store review.
What we build with Flutter
Booking and ordering apps
Where the app is the transaction: pick, schedule, pay, track. Both stores from one build, with the payment flow tested on real devices on both platforms before submission rather than after the first rejection.
Field and driver apps
Apps used on the move, on bad connections, often on cheap Android hardware. Offline-first storage so a job completed in a basement syncs when signal returns rather than being lost — which is the actual requirement behind most field apps.
Customer apps for an existing web platform
When the website already works and the business wants a presence in the stores. The app talks to the same API the web does, so there is one source of truth and no second backend to keep in sync.
Arabic-first apps
Full RTL support is built into the framework rather than added on, so an Arabic layout mirrors correctly instead of being a translated version of a left-to-right design with the text swapped.
How we ship Flutter projects
Store submission is part of the project, not an afterthought. Apple's review rejects first submissions routinely for reasons that are predictable — missing privacy declarations, a login with no delete-account path, screenshots at the wrong sizes — and we handle those before submitting rather than losing a week to a rejection.
Your developer accounts, your app listings, from the start. An app published under an agency account is a hostage, and we have been asked to rescue several.
Tested on real low-end Android hardware, not just a simulator. That is where the performance problems are.
What Flutter costs you
App size is larger than native — Flutter ships its rendering engine with the app, which adds meaningfully to the download. On a market where users watch their data allowance, that is worth knowing before committing.
Anything the platform added last month needs a plugin before Flutter can use it, and occasionally that plugin does not exist yet and we write it. That is a real, if occasional, cost.
And the Dart hiring pool is small. If the plan is an in-house mobile team in Dubai, React Native has more available developers, and we will say so.
App size is larger than a native equivalent — the framework ships with the app. On a low-end Android device with limited storage that occasionally matters, and in most markets it does not.
Deep platform integration is the real limit. Widgets, watch apps, complex background work and anything that has to feel exactly like the operating system are where a native build earns its cost, and we will say so rather than stretch Flutter to cover it.
Flutter questions we get asked
Mobile apps start at $25,000 and typically land between $35,000 and $80,000 for both platforms, depending on how many screens there are, whether it works offline, and what it integrates with. Two native apps covering the same scope generally cost 60–80% more.
Yes — thousands are on the App Store, including from very large companies. Apple rejects apps for policy reasons, not for the toolkit used. The common rejection causes are privacy declarations and account deletion, and we handle both before submitting.
Flutter if the app must look identical on both platforms and match your brand exactly. React Native if you already have a React web team, since they share a language and much of the logic. Both are mature; the deciding factor is usually your existing team.
For most business apps, yes — users cannot tell. Where it shows is the edges: platform-specific gestures, deep system integration and widgets. If those matter to your product, that is the argument for native, and it is a real one.
